is journalism a threat to the state?
"is journalism a threat to the state?"
It ought to be, but rarely is. Legitimate journalism should be a potential threat to anybody (or any organisation) in a position of power or influence, especially where they appear to be unaccountable and misbehaving.
Trafigura has been mentioned. The very same "self denying injunction" principle also applied to the Guardian's coverage earlier this year of Barclay's use of tax dodging by corporates and individuals to create a £1BN/year income stream.
When the Barclays news came out earlier this year it was covered not just in the Guardian but in newspapers as varied as the Daily Mail  and the FT. The Guardian got injuncted but the restriction seems to have been lifted recently at the same time as the Trafigura one.
Although Barclays tax stuff was widely covered in various media, it got zero coverage on the BBC's own output.
In unrelated news, the Chairman of Barclays is a "senior independent director" on the BBC's Executive Board .
"Barclays bank is alleged to be making around £1billion a year from financial schemes aimed at avoiding paying tax in the UK and abroad, it has been reported.
The claim has been made by a whistleblower, who passed internal Barclays documents to Vince Cable, deputy leader of the Liberal Democrats."
